SOURCE: 1999 Chev Venture Heater core do I need to remove

The blower motor location can change from year-to-year. It can also change with the trim level of the vehicle. A vehicle that has front and rear climate controls may be configured differently than a vehicle that has front controls only. The following are two different repair procedures. One is for blower motors located and accessed in the engine compartment, the other is for blower motors mounted inside the vehicle.

REMOVAL AND INSTALLATION

Engine Compartment Mounted

  1. Disconnect the negative battery cable.
  2. Remove the engine air cleaner assembly.
  3. If necessary for clearance, remove the left hand wiper arm linkage.
  4. Detach the wire harness connector from the blower motor.
  5. Disconnect the motor cooling hose.
  6. Remove the blower motor assembly retaining screws
  7. Carefully pull the blower motor assembly out from the firewall.

Is the blower motor working? If not that is what it is. If it is working then check heater coil out, Could be bad heater coil.

Try checking the two pipes that go into and come out of the heater matrix, is one of them hot? if it is there is an air lock within the matrix, Also is the thermostat opening fully? Sorry i know you said you have changed it twice already but take it out check settings when it should open and close, then boil some water and test the thermostat

How do i change 92 chev luminas heater core


It is probably not the heater core do to most times when the heater core goes bad it stars putting water into the interior of the car. It may be the heater core supply valve or the blend door actuator is not working. Try warming the Vehicle, then carefully feel the heater hoses, are they both hot? If one is cooler than the other, You need to flush the core, or do a replacement job on the heater core. Also if the system has a heat control valve on the heater hose, make sure it is working! Also check the thermostat, and the temperature blend door, thats under the dash, in the heater plenum. You can flush this yourself, buy the prestone flush kit and install the tee in the heater return line. Disconnect the heater hose at the waterpump, clamp the hose in back of the tee you installed and back flush till it runs clear.20 mins or so.

How do you change 1992 chev lumina heater core


if the coolant level is at the proper level and the thermostat is good then before you pull the heater core out you can try disconnecting the heater hoses and drain or blow out as much coolant out of the heater core then connect separate hoses to the spigots and fill the heater core with CLR and let it sit for an hour before draining then flush out with water and repeat if necessary this sometimes works and you won`t have to remove the heater core.

1999 Dodge Grand Caravan heat is cold


There are two possibilities, one is the thermostat. Many people remove them which spoils the whole heating / cooling system. Since you changed the thermostat, I would check the heater valve on the heater which allows the hot water to circulate through the heating system.
It may be necessary to remove the heater box and flush the heater core since you talk about a lot of rust, which could have clogged the heater core and / or the pipes leading to the heater.

1996 chev. blazer, heater not getting hot


You may need a thermostat and a coolant flush but one thing you can try first is disconnecting the heater hoses and run a garden hose with low pressure through the heater core both directions.These are commonly known to get plugged heater cores. If flushing the heater core out brings your heat back definitely get a coolant flush. Make sure to dispose of any antfreeze properly.

No heat. Changed the thermostat and flushed the radiator, had heat, now two weeks later no heat. Might be the heater core, yes/no, is it difficult to change? Just wanting to know.Where can I find...


I'ld say yes, heater core. But before swapping it out try this. There are two hoses that lead to your heater core. Disconnect them and add two longer hoses to it. Run one down to a bucket on the floor. The other flush with high water pressure, then there is this acid you can add. WARNING, I DID SAY ACID. It will eat your skin and if you leave in your heater core too long it will eat you core too! After say 2-3 mins flush with high water pressure again. On second flush I'ld flush for a good 10 15 mins to make sure it's all out. Reconnect factory hoses and refill system.

1999 Taurus-NO HEAT-replaced thermostat,flushed heater core,still NO HEAT,ANY SUGGESTIONS?


Sounds like the problem has to be the valve is not opening and thus not allowing the hot coolant to enter the heater coil. Manualy open the valve (engine firewall) and see if heat is present. If this works check your cable from the dash switch as it isn't working the valve properly and needs replacing.

1999 chevy silverado the heater doesn't put out heat. the engine temp comes up to 190 degrees and the fan works but no heat


Check the valve on the upper heater hose and make sure it moves,if it does then you need to have the heater core flushed.You can do it your self by removeing the heater core hoses from the heater core and runnin water through it with a garden hose but a rad shop can do a better job.If you choose to do it yourself pick up a bottle of rad cleaner first and put it in the rad a few days before you flush it.

Low heat from heater


Had same problem. Take off both hoses to the heater core at the fire wall. Using a garden hose with nozel flush with water on the "inlet hose" first(the one hot to touch) then flush the other side. A nasty blackish slim will come out. Oh, cover your distributor with a plastic bag first so it won't get wet. Put the hoses back on, set heat for full high and enjoy your nice warm bravada again!

No heat


if engine temp is normal after running awhile. i would try to flush the heater core.(disconnecting the heater hoses from engine and flushing separately) ford cars and trucks have a "brown coolant" problem and the coolant will eventually clog heater core.
